` IMPROVEMN': IN oHRNs.

'Ihe Schedule refen'ed to in thelg Letters Patent and making part of the samo.

To all 'whom 'it 'may concern Be it known that I, W. L. GORDON, of Dalton, in the county of VVhitlield, and State of Georgia, have invented a new and useful Improvement in Ohurns; and I do hereby declare that the following is a full, clear, and exact description of the construction an'd operation of the same, reference being had-to the 'ac-l companying drawing's, making a part of this specification, in which- Figure 1 is a longitndinal Vertical section, and

Figure2 is a side elevation.

This invention consists in placing within a churn a Vertical shaft, having on its lower end the dasher, and at its upper extremity a horizontal balance-Wheel, and there being, between the cover of the churn and the balance-wheel, a cross-head, slidiug on said shaft, which oross'head is joined, by means of coiniecting-rods, with the free end of a treadle, and is also joined, by means of cords proceedin g from its cxtremities, with the head of the shaft, all in such manner that when the cords have once been wound around the sh'aft, by hand-rotation, and the free end of the treadlc raised, then, by exerting' the treadle, a continuous rotation'of the vertical shaft may be produced.

In the drawings- A is a chum,

o B is a Vertical shaft, placed in the churn, extending up through its cover, and having on its upper end a horizontal balance-wheel, b.

"At the, lower end of the shaft, is the dasher b'.

Midway on the shaft, and vsliding freely therebn, is 'a cross-head, c, joiued,`by means of connecting-rodsc' c', with lthe free end of the treadle '8, the latterl being pivoted at its opposite extremity. The free end of the treadle and the cross-head rise and fall together. I

The crosshead reciprocates in a pair of slotted standards, O O. z i

Cords d d, passed through diametrical holes near raising the cross-head, and drawing up the free e'd of 'the treadle', then by applying the foot to *t treadle, and depressing its free end, the cross-head c,

drawn down, unwinding the. cords, and setting theshaft B in motion. The momentum gained by the' sliaft during one depression of the lever, is suliioient to carry it on until it winds up the cords again i'n the opposite direction, and' isbrought to a standstill by the tightening of the cords. This rewinding of the cords again raises the treadle, so that the moment the shaft stops; it can be set in motion again by depressl iug once more the treadle. on continnously, each'depression of the treadle prodncing motion enough in the shaft to ra-ise the treadle again. The balance-wheel b accumulates momentum during the down-strokcs, and dispenses it to the shaft during the up-strokes, insu'ring the rise of the treadle.

Having thus described my invention, VVhat I olaim as new, and desire to secure by Letters Patent, is-

T hc shaft B, provided with the balance-wheel i), and combined with the cross-head o andtreadle e, snbstantially in the manner described.

To the above specific-ation of my improvement 1 have set my hand, this 3d day of July, 1869.
